mserrnamne WINDOW-SCREEN.

Application filed July 27, 1917, Serial No. 183,991.

T all whom it may concern:

Be it known that I, JAMES K. Scrrmvcn, a citizen of the United States, residing at 1 Seattle, in the county of King and State of Washington, have invented a new and useful Improvement in Disappearing Window- Screens, of which the following is a speclfication. I

This invention relates to improvements in disappearing window screens, and the object of this improvement is tosimplify the details of construction. and make the screen more efficient in operation and more easy'to install on a Window.

This invention 1s 1n the nature of an 1mprovement on the disappearing window screen disclosed in the co-pending application of Harold B. Schenck, Serial Number 90985, filed April 10, 1916, and is directed to improve a means for securing the top edge of the screen to the bottom of the window r is a view in cross section substantially on away; Figs. 4 an broken line 3, 3 of Fig. 1, showing the method of fastenin the housing to the casing and showin the screen roller broken 5 are enlarged views in perspective illustrating the details of the members that are used for connecting the screen to the window sash; Fig. 6 is a view in perspective showing the method of securing the screen to the cross bar; Fig. 7 is a fragmentary view in perspective illustrating the telescopic guide members and the means of securing such guide members to the window casing, and Fig. 8 isa fragmentary view in perspective showing an alternative manner of connecting the screen to the top cross bar.

This screen is hereinshown and described as applied to the lower sash only of a window, but it will be understood that the same maybe applied to the upper sash of a window without any substantial change of form.

Referring to the drawings throughout, in

Specification of Letters Patent.

Renewed December 27, 1918. Serial No. 268,497.

which like reference numerals indicate like parts, the numeral 9 indicates a window frame that is provided with a window sill 10 and with lower and upper sashes 11 and 12 respectively that are adapted to move vertically between stops 13, 14 and 15.

This invention consists of a screen 16 that is secured at one end to a roller 17 and adapted to be wound thereon when it is not in use.

.The roller 17 isprovided with an internally disposed spring 18 and is constructed in substantially the same manner as an ordinary curtain. roller, except that it is made heavier and strongcr'and is of large enough diameter so that it will not damage or de form the screen as it is wound thereon.

The roller is disposed within a housing 20 that is preferably of arcuate cross sectional shape, as shown in Fig. 2, and large enough to contain the screen when it is wound up.

The housing 20 is referably formed of sheet metal and has sleet metal end members 21, one of which has a square hole the end of the spring roller and the other 22 for the reception of a flattened stud on' of which is provided with a hole through which a screw 23 may be inserted into the roller. The roller may be easily removed from the housing by first taking out the screw 23.

The housing 20 is preferably secured to the window casing 9 by two rods 24 that are articulated with a. lever arm 25 on opposite sides of a pivot 26 by which such lever arm is secured to the bottom of the housing, and which extend outwardly in opposite directions through the end plates on the opposite ends of the housing, so that when the lever arm 25, as seen in Fig. 3, is turned to the left the sharpened ends 27 of the bars will be withdrawn into the housing and when the lever arm 25 is turned tothe right, such sharpened ends will be projected outwardly through the ends of the housing and forced into the sides of the wTndow casing, thus securely fastening the housing 20 to the casing 9.

If desired, the method of fastening described above may be dispensed with and the housing may be secured to the window 'sill by screws or nails 60, as indicated by dotted lines in Fig. 3.

. The edge of the screen opposite the roller shaped slots 39 in the edge of the guides" is fastened within a sheet metal cross bar in the other portion with keyhole slots 33 that fit over and are secured upon studs 34 on a plate 35 on the bottom of the sash.

The part 28 is pressed tightly against the screen for the greater portion of its length,

but is left free fromthe screen for a short distance near each end so that the members 31 and 32 may be inserted thereunder.

The portions of the members 31 and 32 "that hook under the part 28 ofthe metal bar are provided with elongated slots36 and the part 28 is indented by stamping as at 37 to form studs or protruding portions that project into the slot- 36 to prevent the members 31 and-32 from becoming detached, and at the same time permit such members to move lengthwise of the crossbar.

The members 31 and 32 areeasily secured to the window sash by slipping the larger portions'of the keyhole slots 33 over the heads of the Studs 34 and then moving such members'sidewise' until the studs 34 are within the narrower portions of; the slots 33.

When-the screen is secured to the win-- dow the bar along the top edge of the screen is held closely against the outside of the bottom rail of the sash, as shown in Fig. 2.

When the screen is detached from the sash the members 31' and 32 will engage with the liousin 20 and prevent the screen from unwin ing.

The members 31 and 32 may be removed from the screen bar by springing the part 28 outwardly.

3.8. are U shaped guides that are secured to the window stop 14 by means of keyhole that may be placed over and secured on nails or tacks 40 that aredriven into the window.

stop.

The guides are adapted for the reception of the edges of the screen and are p'referablymade in two parts and telescoped together, see Fig. 7, so that they may be adjusted to windows of a different size without being out off.

' At the bottom of the guides 38, the outer side thereof may be cut 0d and secured to the housing 20 as shown at 38 and the inner side thereof may extend downward into close proximity to the window sill, as shown at 38%, see Fig. 41 1s a strip preferably offiber board that is secured to the lowerside of the top sash ing claims;

When thezscreen is not in use it, may be left on the window within the housing 20 by which it is protected, or if desired, the

housing and screen may both be removed from the window.

When the window is closed the screen is entirely out of sight and out of the way, thus permitting a clear and unobstructed view through the window, and leaving the outer surface of the window free of access for cleaning, v r

Fig. 8 illustrates an alternative manner of securing the screen to the top cross bar. In this figure the cross bar is formed in the shape of a letter U, with one edge bent inwardly, as indicated at 42, and the top edge of the screen is doubled over and a strip or key 43 .is inserted between the doubled over portion of the screen and the, bent portion 42 of the bar, inthew manner shown to secure the screen .to the cross bar. s v

VVhenthe screen is secured to the cross bar in this manner, it may be easily removed by taking out the key 4 f It is obvious that changes in the form of the various parts herein disclosed may be resorted to within the scope of the follow What I claim and desire to protect by Letters Patent is: v
